Sorry - another link, about efforts to close down cellphones in cinemas
and the like.
When an incoming signal is very weak, cellphones presumably ramp up the
power of their own signals. So if this tech. "half worked" it would lead
to all the cellphones in the cinema blasting away on full power all
trying to contact the nearest base station....
What do cellphones do when the signal is non-existant? Do they just put
out a very low power signal? Or do they blast away?
